Definitions

  • the invention relates to a ship propulsion system with a plurality of electric drive shafts according to claim 1 and an advantageous use of such a Schiffsantriebssys ⁇ system according to claim 16.
  • Electric drive systems on ships usually comprise one or more electric drive motors for driving in each case a propulsion unit (eg a propeller), which in each case via an inverter from an electrical network of the ship (often referred to as “driving network") are fed
  • the electrical network is in turn fed by one or more diesel generators, the electrical network having a voltage of fixed amplitude and frequency, eg a medium voltage with a rated voltage of 6.6 kV at a nominal frequency of 60 Hz., Where appropriate, between the inverter and the power still connected a transformer.
  • the inverters convert the (possibly stepped-down) AC voltage into ei ⁇ ne required for the operation of the drive motors with voltage from the supply voltage of different amplitude and frequency.
  • Low-voltage consumers on board a ship are supplied by a separate vehicle electrical system, which usually has a rated voltage of 400 V at a nominal frequency of 50 Hz or 440 V at 60 Hz.
  • the electrical system can be powered independently of the driving network of its own on-board generators with electrical energy.
  • the vehicle electrical system can be supplied via a vehicle power converter and, if necessary, a transformer from the vehicle network. The on-board converter and, if necessary, the transformer converts the voltage of the driving network into a voltage with the amplitude and frequency of the vehicle electrical system.
  • a big advantage of this solution is that the converter can avoid repercussions on the drive network due to load surges (eg when a propeller dives up and down the water in heavy seas), if it is dimensioned accordingly large.
  • these drive concepts have the disadvantage that they require a larger number of converters for voltage conversion in the transport network with corresponding space requirements and costs.
  • Another known electric drive solution which manages without such converters, is to couple the generators and the drive motors without intermediate converters with each other.
  • one or more variable speed drive motors are operated without interposed inverter directly with the variable amplitude and variable frequency voltage generated by one or more variable speed generators.
  • the control and / or regulation of the motors and thus the propulsion units is thus indirectly by a Steue ⁇ tion and / or regulation of the internal combustion engines for driving the generators.
  • the drive motors are coupled electri- cally determined with the generators, ie, a Drehbewe ⁇ supply of the generators causes a corresponding proportional rotary movement of the electric drive motors.
  • a mechanical shaft is simulated by means of electrical machines.
  • Such a drive solution is often referred to as an "electric wave".
  • auxiliary power converter converts the ggf- of the (the) Genera ⁇ tor (s) generated voltage of variable amplitude and variable frequency into a voltage with constant amplitude and constant frequency for a vehicle electrical system.
  • More hull vessels such as catamarans and trimarans with Ge ⁇ speeds of over 40 knots are particularly suitable for express ferries and Navy applications which require high speeds. They are therefore enjoying increasing popularity. These vessels have for the excavation, for example, water jets, which are mechanically coupled directly with the ⁇ diesel engines or gas turbines, and are driven by these. Due to the mechanical direct drive, however, there are restrictions in the design of the ship, which prevent an optimal shipbuilding design of the ship (among other things under the aspects of hydrodynamics and functionality).
  • a ship propulsion system comprises at least a first and a second electric drive shaft for at ⁇ operating a respective propulsion unit, in particular a Wa ⁇ terjets, each of said electrical drive shafts at least one is driven by an internal combustion engine speed-variable generator for generating a motor voltage of variable amplitude and variable frequency, and at least supplied a with this motor voltage and with a propulsion unit coupled variable speed variable drive motor comprises.
  • the first and the second drive shaft are switchable from a first operating state in which they are electrically separated from each other into a second operating state in which they are electrically coupled to one another such that an energy transfer from the at least one gene Rator of a drive shaft to the at least one on ⁇ drive motor of the other drive shaft can be done.
  • the total energy consumption of the ship propulsion system can be optimized, since for example in niedri ⁇ gen speed range, in which the internal combustion engines operate with relatively poor efficiency, selectively shuts off the power generation of a drive shaft and the required for the operation of their drive motors electrical energy from one or more generators of the other Drive shaft generated and handed over.
  • the ship propulsion system also comprises a third electric drive shaft for driving a further pre ⁇ drive unit, in particular a waterjet, wherein the third drive shaft at least one of a Verbrennungskraftma- engine driven variable speed generator for generating a motor voltage with variable amplitude and variable Frequency and at least one supplied with this motor voltage and coupled to the further propulsion unit variable speed drive motor comprises, and wherein the first and the third drive shaft of a first operating ⁇ state in which they are electrically separated from each other, are switchable to a second operating state in which they are electrically coupled together such that a Ener ⁇ gieübergabe of the at least one generator of a drive shaft can be made to the at least one drive motor of the other drive shaft.
  • the driving force and thus, for example, the maximum speed of the ship
  • the reliability and energy efficiency can be further increased.
  • the at least one generator is a Supralei ⁇ ter-winding, in particular a high-temperature superconductor (HTS) - winding on.
  • the superconductor winding can be a stator winding or a rotating rotor winding of the generator.
  • Generators in superconductor technology have a higher power density (ie power relative to the construction volume) compared to conventional machines. As a result, even further optimizations in the ship design are possible. By the comparatively lower weight, the speed and / or the payload of the ship can he be ⁇ höht for the same drive line.
  • a generator with a superconductor winding usually has a much larger magnetic air gap between rotor and stator compared to a conventional generator without superconductor winding. This is mainly due to the fact that the superconductor is cooled by a vacuum cryostat or a similar cooling device, whose or whose wall runs in the air gap.
  • the relatively large magnetic air gap causes the Genera ⁇ tor has a much lower synchronous reactance than a conventional generator.
  • a HTS generator is much stiffer compared to a conventional generator
  • the at least one drive motor a superconductor winding, in particular a high-temperature superconductor
  • HTS Winding
  • the superconductor winding is a rotating rotor winding, since in this the surface to be cooled can be kept smaller than in a superconductor stator winding.
  • the coupling of the drive shafts can take place particularly low-loss by an electrical line connection, which preferably comprises a superconductor, in particular a high-temperature superconductor (HTS).
  • an electrical line connection which preferably comprises a superconductor, in particular a high-temperature superconductor (HTS).
  • HTS high-temperature superconductor
  • the second and the third drive shaft serve as the main drive for ei ⁇ nen lower speed range of the ship (eg from zero to 30 knots) and the first drive shaft alone or in combination with the second and the third drive shaft as the main drive for a higher Speed range up to the maximum speed (eg up to 45 knots) of the ship.
  • the internal combustion engine of the first drive shaft is advantageous as a gas turbine and the combustion ⁇ engines of the second and the third drive shaft are advantageously designed as diesel engines.
  • the marine propulsion system preferably includes one with the variable amplitude, variable frequency motor voltage one of the drive shafts powered on-board converter, which converts this motor voltage into a voltage of constant amplitude and constant frequency for a vehicle electrical system.
  • the at least one generator of the drive shaft has a superconductor winding and thus the drive shaft is characterized by a particular rigidity.
  • the ship ⁇ drive system may also include one of the motor voltage of variable amplitude and variable frequency of the second drive shaft powered first auxiliary power converter, which converts this voltage into a voltage with a constant amplitude and a constant frequency for a first vehicle electrical system, and with Variable amplitude and variable frequency motor voltage of the third drive shaft supplied second auxiliary power converter, which converts this voltage into a voltage of constant amplitude and constant frequency for a second sub-board network include.
  • the ship propulsion system comprises at least one additional on-board network generator for supplying the electrical system or a sectionbord ⁇ network with a voltage of constant amplitude and constant frequency.
  • the power supply of the electrical system can be ensured, even if the electric drive shaft is switched off (eg in the harbor) or if the entire generator power of the drive shaft for drive ⁇ purposes is needed.
  • the at least one generator of the drive shaft from the driving internal combustion engine it optionally with egg ⁇ ner fixed or at a variable frequency can be driven, there are other uses of these components.
  • the at least one generator can be used to port ⁇ power supply other ships.
  • the drive shaft on an operating state wherein the at least one generator of the drive shaft is electrically connected to the at least one drive motor of the drive shaft is coupled without interposition of a static converter and a tension ⁇ voltage of variable amplitude and frequency generated in a Operational state switchable, in which the at least one generator of the drive shaft is electrically coupled via an auxiliary power converter with the at least one drive motor of the drive shaft, wherein the auxiliary power converter generates a voltage of variable amplitude and frequency.
  • first operating state can then be changed for small speed requirements of the internal combustion engine to drive the generator, in particular ⁇ for special speed demands that are below a minimum speed requirement of the internal combustion engine, in the second operating state in which the on-board power converter in the electrical drive shaft, that is in the electrical connection between the at least one gene ⁇ generator and the at least one drive motor of the drive shaft, is connected.
  • the drive motor can then be supplied with a voltage which has a lower frequency than the voltage generated by the generator.
  • the drive motor can then drive the propulsion unit even at low speeds with a relatively high torque. As a result, no variable pitch propeller is necessary for low speeds, but it can be used a fixed pitch propeller.
  • the drive shaft of ei ⁇ nem operating state in which the at least one generator of the drive shaft is electrically coupled to the at least one drive motor of the drive shaft without an intermediate circuit of the electrical system converter and generates a voltage variable amplitude and frequency ⁇
  • a Operating state switching ⁇ bar in which the electrical system or sub-board network is electrically coupled via the electrical system converter with the at least one drive motor of the drive shaft, wherein the electrical system ⁇ richter generates a voltage variable amplitude and frequency.
  • the drive motor can also drive the propulsion unit at low speeds with a relatively high torque.
  • the drive motor can be supplied from the electrical system in case of failure of the generators of the electric wave.
